u-boot debugging

[atul.sabharwal at exgate.tek.com]

My best guess is the PowerTap Pro supports code tracing from a trace buffer on the board or processor... Not sure if

you can sample the processor instruction stream over the JTAG chain as its too slow.  You could use a logic analyzer

or an in-circuit emulator to capture all signals.  The power pc has a SIU to pass the instruction stream for a logic analyzer

to use...

BDI works but PowerTap Pro from Metrowerks is better.  The debug interface is windows based and more user friendly than

Ddd on Linux.  Take your pick as a commercial product would be better than an opensource product till it has been perfected

(i.e. customized, all bugs fixed and usability issues resolved).  And no service from the community on occasion.
